Ok..had the same problem today..and had to have a mechanic come to my house and fix it. Heres what u do to disarm and reset the alarm set on the 98 dodge grand caravan without using a remote. Roll down driver side window, hit the lock switch on the driver door panel to unlock all doors, stick arm through window and place key in ignition to the on postion(dont. open car door & dont turn car on) disconnect the battery cable for 5 minutes, replace battery cable, and alarm set indicator on dash board should be off. Turn car on and the alarm has been reset and will allow u to drive.
